Abstract Three new heterobimetallic 1D coordination polymers have been obtained by assembling the [Ni(bpca) 2 ] complex, as a building block, with lanthanide cations: [{Ln(O 2 NO)(H 2 O) 3 }{Ni(bpca) 2 }](NO 3 ) 2 · 3H 2 O (Ln Gd 1 ; Tb 2 ; Dy 3 ). The three compounds are isostructural and their structure consists of…

Theoretical study of size-dependent properties of BN nanotubes with intrinsic defects

Gaoyang Gou、Bicai Pan、L. Shi2007-10-17Physical Review B

Intrinsic defects in zigzag BN nanotubes, including single vacancy, divacancy, and Stone-Wales defects, are systematically investigated using density functional calculation. It is found that the structural configurations and formation energies of the topological defects in considered tubes are dependent on tube diamet…

Optimal Conditions for Labelling of 3T3 Fibroblasts with Magnetoliposomes without Affecting Cellular Viability

Stefaan J. Soenen、Johan Baert、Marcel De Cuyper2007-10-17ChemBioChem

A comparative study that deals with the internalisation of different types of magnetoliposomes (MLs) by 3T3 fibroblasts revealed that cationic MLs proved to be superior to neutral and anionic ones. Internalisation was visualised both by optical light and transmission electron microscopy. The latter showed that the cat…
